摘要
本文报道了四个地区五个工厂(1979～1988年)汞作业点18539次汞蒸气浓度的测定,和227名连续接汞十年的工人进行动态健康监护的结果,证实汞接触水平与尿汞量之间,以及神衰症侯群、汞毒性细小震颤、口腔炎和精神症状与汞接触水平之间均存在剂量反应关系。汞接触十年,当接触水平低于0.01mg/m^3时,无中毒病例发生;接触水平≤0.03mg/m^3,汞中毒为1.9%,神衰症侯群为22.2%,震颤为3.7%,口腔炎为9.3%;接触水平≤).06mg/m^3,汞中毒为17.4%,神衰症侯群,口腔炎和震颤各为39.1%、21.7%和15.2%。根据我国现有防汞技术设施水平,结合国情,以保护接触汞的95%人群不发生中毒,建议汞的卫生标准由原0.01mg/m^3修订为0.03mg/m^3。
Monitoring data obtained from 18539 measurements of air mercury concentration in workplace, surveillance data from the annual routine medical surveillance records of 227 employeas from 1979～1988 were analysed. Exposure-response relationships were found among air mercury concentration and urinary mercury concentration, incidences of neurasthenia, tremor, stomatitis and mercurialism.
After exposure to mercury for ten years, no mereurialism but 19.7% neurasthenia at the level below 0.01rag/m^3; 1.9% mercurialism, 22.2% neurasthenia, 3.7% tremor and 9.3% stomatitis at the level ≤0.03mg/m^3; 17.4% mercurialism, 39.1% neurasthenia, 21.7% stomatitis and 15.2% tremor at the level about 0.06mg/m^3.
According to the technical mercury-control level in China, in order to protect 95% mercury-exposure workers from mercurialism. We suggest that hygienic standard of metallic mercury in workplace would be possible to amend from 0.01 to 0.03mg/m^3.
